Abstract
A voltage transformer with a sequentially switchable voltage selection circuit is provided for converting input electrical energy through the sequentially switchable voltage selection circuit, which is arranged within the transformer body with its two ends electrically connected to an input port and an output port respectively, into one of a plurality of output voltage values and outputting the electrical energy. When it is desired to regulate an output voltage, a connection device must be plugged in a socket portion on the transformer body to initialize a micro control unit through feedback to change a voltage value sent to a voltage transformation unit, and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected predetermined voltage value to output the electrical energy.
